Title: Process for transmitting and/or storing digital signals of multiple channels
Inventor: EBERLEIN ERNST
IPC: G11B20/00
Filed: 1993-11-02
Abstract: Disclosed is a process for transmitting and/or storing digital signals of multiple channels. This process is suited, in particular, for transmitting the five channels of 3/2 stereophony as well as for transmitting two stereo channels and three additional commentary channels. In this manner, by way of illustration, television programms with multi-language audio signals can be transmitted.        This process is distinguished that by reduction of the to-be-transmitted data, only a bit rate of 384 kbit/s is required for transmission.        The reduction of the data is achieved by the K input channels being imaged in segments onto the N<=K virtual spectral data channels, by the spectral data channels being quantized, coded and transmitted taking into consideration the principles of psychoacoustics and by K output channels being reproduced from the transmitted bit stream with the aid of a also transmitted list from the N<=K spectral data channels.

Title: Constant inertial rotor speed drive
Inventor: WILSON STANLEY EDWARD GEORGE
IPC: G01C19/06
Filed: 1996-06-06
Abstract: Improved method and means to initiate and maintain a rotor at substantially constant speed with respect to an inertial frame of reference, comprising surrounding the rotor with a rotor enclosure which rotates substantially in step with the rotor in order to isolate the rotor from contact with the outside environment and to provide a stationary relative environment for the rotor. In the preferred embodiment the rotor, of conventional cylindrical shape, is maintained within a similarly shaped rotor enclosure by rotor support means which comprises anti-friction bearings. The rotor enclosure is driven by a stepper motor: at startup, a simple mechanical clutch mechanism is employed to couple the rotor to the rotor enclosure to initiate motion of the rotor. An optical pickoff detects marks on the rotor through an optically transparent portion of the rotor enclosure and generates a signal which is employed to control the stepper motor and thereby the motion of the rotor enclosure. Various alternative embodiments of the invention are feasible. Alternative enclosure drive means include brushless D.C. motors and switched reluctance motors.  Alternative rotor support means include nested bearings and flexure supports, and alternative rotor support methods include dithering and selective torque rectification. Alternative pickoff means include various precisions of incremental or absolute encoders. Alternative overall arrangements of the means of the invention include locating an 'inside-out' drive motor within the rotor.

Title: Natural gas production optimization switching valve system
Inventor: MCLEAN DAN J
IPC: E21B43/12
Filed: 1996-12-11
Abstract: Producing natural gas wells with high GLR (Gas Liquid Ratios) have been the source of many operational problems, especially during Canadian winters. Automation technology now allows us to relieve the wellbore of these liquids in a controlled manner, thus freeing production casing capacity where problem wells are produced by the tubing string. This invention deals with the implementation of Switching Valve technology with an electronic controller and a custom algorithym to optimize the production through three principal methods. The first is by using the casing as the primary production string. This is advantageous as the casing area is larger than that of the tubing and thus allows a greater flow rate. The second is by preventing the need to shut in the well when liquid loading occurs. This allows some portion of the flow to be maintained while the liquid is being removed. Lastly the Switching Valve technology provides a method to automatically maintain lower liquid levels within the well to ensure the highest flow rate.
